I've gotten it a few times and now it'* on steady. Anyone have a trouble shooting chart/ideas or even more info other than the T/C name?
Thanks.

Im no gearhead, but I think it has something to do with low voltage.

I can only suggest looking at the PCM C2 connector (80 pin) pin 5. The MIL control ckt. comes through pin 5. The only other thing I'd say is try disconnecting the battery for a few minutes, then reconnect to reboot the PCM. DTC P0650 means that there is an improper voltage level detected on Output Driver Module D output 1 (MIL control ckt.)

Check all your relays and fuses for good contact.
All it takes is a loose fuse to cause all kinds of grief.

Ok, I checked and a couple of fuses in the eng box were not completely seated. Took PWR off the car and I'll see how she behaves. I think it knows I'm going to sell it.

Hope that fixed it.
I cost me $200 to find that out.
That'* what this club is all about. Maybe some day you can help others.
